Corporation Bridge Scherzer rolling-lift bascule bridge machinery and control building in Grimsby, North East Lincolnshire, England, UK. The photograph concentrates on the industrial operating structure above the road crossing, showing the steel framework, bridge machinery and elevated control accommodation associated with the historic movable span over Alexandra Dock. Corporation Bridge is a rare surviving example of the Scherzer rolling-lift principle, in which the lifting section moves back on curved tracks as it opens to provide clearance for vessels. The bridge forms part of Grimsby's dockside engineering heritage and reflects the importance of movable bridges to ports where road traffic and navigation had to share constrained industrial waterways. The image is suitable for editorial use relating to bridge engineering, bascule mechanisms, industrial architecture, listed heritage, dock infrastructure, transport history, maritime trade and the regeneration and conservation of historic structures in Grimsby.
